Attached Files:

what format is your external drive(s)? check in disk utility by selecting it and looking at format down the bottom. if its fat32 then theres your problem. fat32 has a 4gb (i think? definitely less than 7gb though) limit.

format it to HFS+ and youll have no problems. this will delete everything on it so back it up in small 4gb pieces
